MEDICATIONS FOR
MENTAL ILLNESS
This page describes
medications by their generic (chemical) names
and in italics by their trade names (brand names
used by pharmaceutical companies). They are
divided into four large
categories—antipsychotic, antimanic,
antidepressant, and antianxiety medications.
Medications that specifically affect children,
the elderly, and women during the reproductive
years are also discussed.
Lists at the end of
the page give the generic name and the
trade name of the most commonly prescribed
medications. A separate chart shows the trade
and generic names of medications commonly
prescribed for children and
adolescents.
Treatment evaluation
studies have established the effectiveness of
the medications described here, but much remains
to be learned about them. The National Institute
of Mental Health, other Federal agencies, and
private research groups are sponsoring studies
of these medications. Scientists are hoping to
improve their understanding of how and why these
medications work, how to control or eliminate
unwanted side effects, and how to make the
medications more effective.
ANTIPSYCHOTIC
MEDICATIONS
A person who is psychotic
is out of touch with reality. People with
psychosis may hear "voices" or have strange and
illogical ideas (for example, thinking that
others can hear their thoughts, or are trying to
harm them, or that they are the President of the
United States or some other famous person). They
may get excited or angry for no apparent reason,
or spend a lot of time by themselves, or in bed,
sleeping during the day and staying awake at
night. The person may neglect appearance, not
bathing or changing clothes, and may be hard to
talk to—barely talking or saying things that
make no sense. They often are initially unaware
that their condition is an illness.
These kinds of behaviors
are symptoms of a psychotic illness such as
schizophrenia. Antipsychotic medications act
against these symptoms. These medications cannot
"cure" the illness, but they can take away many
of the symptoms or make them milder. In some
cases, they can shorten the course of an episode
of the illness as well.
There are a number of
antipsychotic (neuroleptic) medications
available. These medications affect
neurotransmitters that allow communication
between nerve cells. One such neurotransmitter,
dopamine, is thought to be relevant to
schizophrenia symptoms. All these medications
have been shown to be effective for
schizophrenia. The main differences are in the
potency—that is, the dosage (amount) prescribed
to produce therapeutic effects—and the side
effects. Some people might think that the higher
the dose of medication prescribed, the more
serious the illness; but this is not always
true.
The first antipsychotic
medications were introduced in the 1950s.
Antipsychotic medications have helped many
patients with psychosis lead a more normal and
fulfilling life by alleviating such symptoms as
hallucinations, both visual and auditory, and
paranoid thoughts. However, the early
antipsychotic medications often have unpleasant
side effects, such as muscle stiffness, tremor,
and abnormal movements, leading researchers to
continue their search for better
drugs.
The 1990s saw the
development of several new drugs for
schizophrenia, called "atypical
antipsychotics." Because they have fewer
side effects than the older drugs, today they
are often used as a first-line treatment. The
first atypical antipsychotic, clozapine
(Clozaril), was introduced in the United
States in 1990. In clinical trials, this
medication was found to be more effective than
conventional or "typical" antipsychotic
medications in individuals with
treatment-resistant schizophrenia (schizophrenia
that has not responded to other drugs), and the
risk of tardive dyskinesia (a movement disorder)
was lower. However, because of the potential
side effect of a serious blood
disorder—agranulocytosis (loss of the white
blood cells that fight infection)—patients who
are on clozapine must have a blood test every 1
or 2 weeks. The inconvenience and cost of blood
tests and the medication itself have made
maintenance on clozapine difficult for many
people. Clozapine, however, continues to be the
drug of choice for treatment-resistant
schizophrenia patients.
Several other atypical
antipsychotics have been developed since
clozapine was introduced. The first was
risperidone (Risperdal), followed by
olanzapine (Zyprexa), quetiapine
(Seroquel), and ziprasidone
(Geodon). Each has a unique side effect
profile, but in general, these medications are
better tolerated than the earlier
drugs.
All these medications have
their place in the treatment of schizophrenia,
and doctors will choose among them. They will
consider the person's symptoms, age, weight, and
personal and family medication
history.
Dosages
and side effects. Some drugs are very
potent and the doctor may prescribe a low dose.
Other drugs are not as potent and a higher dose
may be prescribed.
Unlike some prescription
drugs, which must be taken several times during
the day, some antipsychotic medications can be
taken just once a day. In order to reduce
daytime side effects such as sleepiness, some
medications can be taken at bedtime. Some
antipsychotic medications are available in
"depot" forms that can be injected once or twice
a month.
Most side effects of
antipsychotic medications are mild. Many common
ones lessen or disappear after the first few
weeks of treatment. These include drowsiness,
rapid heartbeat, and dizziness when changing
position.
Some people gain weight
while taking medications and need to pay extra
attention to diet and exercise to control their
weight. Other side effects may include a
decrease in sexual ability or interest, problems
with menstrual periods, sunburn, or skin rashes.
If a side effect occurs, the doctor should be
told. He or she may prescribe a different
medication, change the dosage or schedule, or
prescribe an additional medication to control
the side effects.
Just as people vary in
their responses to antipsychotic medications,
they also vary in how quickly they improve. Some
symptoms may diminish in days; others take weeks
or months. Many people see substantial
improvement by the sixth week of treatment. If
there is no improvement, the doctor may try a
different type of medication. The doctor cannot
tell beforehand which medication will work for a
person. Sometimes a person must try several
medications before finding one that
works.
If a person is feeling
better or even completely well, the medication
should not be stopped without talking to the
doctor. It may be necessary to stay on the
medication to continue feeling well. If, after
consultation with the doctor, the decision is
made to discontinue the medication, it is
important to continue to see the doctor while
tapering off medication. Many people with
bipolar disorder, for instance, require
antipsychotic medication only for a limited time
during a manic episode until mood-stabilizing
medication takes effect. On the other hand, some
people may need to take antipsychotic medication
for an extended period of time. These people
usually have chronic (long-term, continuous)
schizophrenic disorders, or have a history of
repeated schizophrenic episodes, and are likely
to become ill again. Also, in some cases a
person who has experienced one or two severe
episodes may need medication indefinitely. In
these cases, medication may be continued in as
low a dosage as possible to maintain control of
symptoms. This approach, called maintenance
treatment, prevents relapse in many people and
removes or reduces symptoms for
others.
Multiple medications.
Antipsychotic medications can produce unwanted
effects when taken with other medications.
Therefore, the doctor should be told about all
medicines being taken, including
over-the-counter medications and vitamin,
mineral, and herbal supplements, and the extent
of alcohol use. Some antipsychotic medications
interfere with antihypertensive medications
(taken for high blood pressure), anticonvulsants
(taken for epilepsy), and medications used for
Parkinson's disease. Other antipsychotics add to
the effect of alcohol and other central nervous
system depressants such as antihistamines,
antidepressants, barbiturates, some sleeping and
pain medications, and narcotics.
Other
effects. Long-term treatment of
schizophrenia with one of the older, or
"conventional," antipsychotics may cause a
person to develop tardive dyskinesia (TD).
Tardive dyskinesia is a condition characterized
by involuntary movements, most often around the
mouth. It may range from mild to severe. In some
people, it cannot be reversed, while others
recover partially or completely. Tardive
dyskinesia is sometimes seen in people with
schizophrenia who have never been treated with
an antipsychotic medication; this is called
"spontaneous dyskinesia." However, it is most
often seen after long-term treatment with older
antipsychotic medications. The risk has been
reduced with the newer "atypical" medications.
There is a higher incidence in women, and the
risk rises with age. The possible risks of
long-term treatment with an antipsychotic
medication must be weighed against the benefits
in each case. The risk for TD is 5 percent per
year with older medications; it is less with the
newer medications.
ANTIMANIC MEDICATIONS
Bipolar disorder is
characterized by cycling mood changes: severe
highs (mania) and lows (depression). Episodes
may be predominantly manic or depressive, with
normal mood between episodes. Mood swings may
follow each other very closely, within days
(rapid cycling), or may be separated by months
to years. The "highs" and "lows" may vary in
intensity and severity and can co-exist in
"mixed" episodes.
When people are in a manic
"high," they may be overactive, overly
talkative, have a great deal of energy, and have
much less need for sleep than normal. They may
switch quickly from one topic to another, as if
they cannot get their thoughts out fast enough.
Their attention span is often short, and they
can be easily distracted. Sometimes people who
are "high" are irritable or angry and have false
or inflated ideas about their position or
importance in the world. They may be very
elated, and full of grand schemes that might
range from business deals to romantic sprees.
Often, they show poor judgment in these
ventures. Mania, untreated, may worsen to a
psychotic state.
In a depressive cycle the
person may have a "low" mood with difficulty
concentrating; lack of energy, with slowed
thinking and movements; changes in eating and
sleeping patterns (usually increases of both in
bipolar depression); feelings of hopelessness,
helplessness, sadness, worthlessness, guilt;
and, sometimes, thoughts of suicide.
Lithium. The medication used
most often to treat bipolar disorder is lithium.
Lithium evens out mood swings in both
directions—from mania to depression, and
depression to mania—so it is used not just for
manic attacks or flare-ups of the illness but
also as an ongoing maintenance treatment for
bipolar disorder.
Although lithium will
reduce severe manic symptoms in about 5 to 14
days, it may be weeks to several months before
the condition is fully controlled. Antipsychotic
medications are sometimes used in the first
several days of treatment to control manic
symptoms until the lithium begins to take
effect. Antidepressants may also be added to
lithium during the depressive phase of bipolar
disorder. If given in the absence of lithium or
another mood stabilizer, antidepressants may
provoke a switch into mania in people with
bipolar disorder.
A person may have one
episode of bipolar disorder and never have
another, or be free of illness for several
years. But for those who have more than one
manic episode, doctors usually give serious
consideration to maintenance (continuing)
treatment with lithium.
Some people respond well
to maintenance treatment and have no further
episodes. Others may have moderate mood swings
that lessen as treatment continues, or have less
frequent or less severe episodes. Unfortunately,
some people with bipolar disorder may not be
helped at all by lithium. Response to treatment
with lithium varies, and it cannot be determined
beforehand who will or will not respond to
treatment.
Regular blood tests are an
important part of treatment with lithium. If too
little is taken, lithium will not be effective.
If too much is taken, a variety of side effects
may occur. The range between an effective dose
and a toxic one is small. Blood lithium levels
are checked at the beginning of treatment to
determine the best lithium dosage. Once a person
is stable and on a maintenance dosage, the
lithium level should be checked every few
months. How much lithium people need to take may
vary over time, depending on how ill they are,
their body chemistry, and their physical
condition.
Side
effects of lithium. When people first
take lithium, they may experience side effects
such as drowsiness, weakness, nausea, fatigue,
hand tremor, or increased thirst and urination.
Some may disappear or decrease quickly, although
hand tremor may persist. Weight gain may also
occur. Dieting will help, but crash diets should
be avoided because they may raise or lower the
lithium level. Drinking low-calorie or
no-calorie beverages, especially water, will
help keep weight down. Kidney changes—increased
urination and, in children, enuresis (bed
wetting)—may develop during treatment. These
changes are generally manageable and are reduced
by lowering the dosage. Because lithium may
cause the thyroid gland to become underactive
(hypothyroidism) or sometimes enlarged (goiter),
thyroid function monitoring is a part of the
therapy. To restore normal thyroid function,
thyroid hormone may be given along with
lithium.
Because of possible
complications, doctors either may not recommend
lithium or may prescribe it with caution when a
person has thyroid, kidney, or heart disorders,
epilepsy, or brain damage. Women of childbearing
age should be aware that lithium increases the
risk of congenital malformations in babies.
Special caution should be taken during the first
3 months of pregnancy.
Anything that lowers the
level of sodium in the body—reduced intake of
table salt, a switch to a low-salt diet, heavy
sweating from an unusual amount of exercise or a
very hot climate, fever, vomiting, or
diarrhea—may cause a lithium buildup and lead to
toxicity. It is important to be aware of
conditions that lower sodium or cause
dehydration and to tell the doctor if any of
these conditions are present so the dose can be
changed.
Lithium, when combined
with certain other medications, can have
unwanted effects. Some diuretics—substances that
remove water from the body—increase the level of
lithium and can cause toxicity. Other diuretics,
like coffee and tea, can lower the level of
lithium. Signs of lithium toxicity may include
nausea, vomiting, drowsiness, mental dullness,
slurred speech, blurred vision, confusion,
dizziness, muscle twitching, irregular
heartbeat, and, ultimately, seizures. A
lithium overdose can be life-threatening. People
who are taking lithium should tell every doctor
who is treating them, including dentists, about
all medications they are taking.
With regular monitoring,
lithium is a safe and effective drug that
enables many people, who otherwise would suffer
from incapacitating mood swings, to lead normal
lives.
Anticonvulsants. Some people
with symptoms of mania who do not benefit from
or would prefer to avoid lithium have been found
to respond to anticonvulsant medications
commonly prescribed to treat
seizures.
The anticonvulsant
valproic acid (Depakote, divalproex
sodium) is the main alternative therapy for
bipolar disorder. It is as effective in
non-rapid-cycling bipolar disorder as lithium
and appears to be superior to lithium in
rapid-cycling bipolar disorder. Although valproic
acid can cause gastrointestinal side effects,
the incidence is low. Other adverse effects
occasionally reported are headache, double
vision, dizziness, anxiety, or confusion.
Because in some cases valproic acid has caused
liver dysfunction, liver function tests should
be performed before therapy and at frequent
intervals thereafter, particularly during the
first 6 months of therapy.
Other anticonvulsants used
for bipolar disorder include carbamazepine
(Tegretol), lamotrigine
(Lamictal), gabapentin
(Neurontin), and topiramate
(Topamax). The evidence for
anticonvulsant effectiveness is stronger for
acute mania than for long-term maintenance of
bipolar disorder. Some studies suggest
particular efficacy of lamotrigine in bipolar
depression. At present, the lack of formal FDA
approval of anticonvulsants other than valproic
acid for bipolar disorder may limit insurance
coverage for these medications.
Most people who have
bipolar disorder take more than one medication.
Along with the mood stabilizer—lithium and/or an
anticonvulsant—they may take a medication for
accompanying agitation, anxiety, insomnia, or
depression. It is important to continue taking
the mood stabilizer when taking an
antidepressant because research has shown that
treatment with an antidepressant alone increases
the risk that the patient will switch to mania
or hypomania, or develop rapid
cycling.
Sometimes, when a bipolar patient
is not responsive to other medications, an
atypical antipsychotic medication is prescribed.
Finding the best possible medication, or
combination of medications, is of utmost
importance to the patient and requires close
monitoring by a doctor and strict adherence to
the recommended treatment regimen.
ANTIDEPRESSANT MEDICATIONS
Major depression, the kind
of depression that will most likely benefit from
treatment with medications, is more than just
"the blues." It is a condition that lasts 2
weeks or more, and interferes with a person's
ability to carry on daily tasks and enjoy
activities that previously brought pleasure.
Depression is associated with abnormal
functioning of the brain. An interaction between
genetic tendency and life history appears to
determine a person's chance of becoming
depressed. Episodes of depression may be
triggered by stress, difficult life events, side
effects of medications, or medication/substance
withdrawal, or even viral infections that can
affect the brain.
Depressed people will seem
sad, or "down," or may be unable to enjoy their
normal activities. They may have no appetite and
lose weight (although some people eat more and
gain weight when depressed). They may sleep too
much or too little, have difficulty going to
sleep, sleep restlessly, or awaken very early in
the morning. They may speak of feeling guilty,
worthless, or hopeless; they may lack energy or
be jumpy and agitated. They may think about
killing themselves and may even make a suicide
attempt. Some depressed people have delusions
(false, fixed ideas) about poverty, sickness, or
sinfulness that are related to their depression.
Often feelings of depression are worse at a
particular time of day, for instance, every
morning or every evening.
Not everyone who is
depressed has all these symptoms, but everyone
who is depressed has at least some of them,
co-existing, on most days. Depression can range
in intensity from mild to severe. Depression can
co-occur with other medical disorders such as
cancer, heart disease, stroke, Parkinson's
disease, Alzheimer's disease, and diabetes. In
such cases, the depression is often overlooked
and is not treated. If the depression is
recognized and treated, a person's quality of
life can be greatly improved.
Antidepressants are used
most often for serious depressions, but they can
also be helpful for some milder depressions.
Antidepressants are not "uppers" or stimulants,
but rather take away or reduce the symptoms of
depression and help depressed people feel the
way they did before they became
depressed.
The doctor chooses an
antidepressant based on the individual's
symptoms. Some people notice improvement in the
first couple of weeks; but usually the
medication must be taken regularly for at least
6 weeks and, in some cases, as many as 8 weeks
before the full therapeutic effect occurs. If
there is little or no change in symptoms after 6
or 8 weeks, the doctor may prescribe a different
medication or add a second medication such as
lithium, to augment the action of the original
antidepressant. Because there is no way of
knowing beforehand which medication will be
effective, the doctor may have to prescribe
first one and then another. To give a medication
time to be effective and to prevent a relapse of
the depression once the patient is responding to
an antidepressant, the medication should be
continued for 6 to 12 months, or in some cases
longer, carefully following the doctor's
instructions. When a patient and the doctor feel
that medication can be discontinued, withdrawal
should be discussed as to how best to taper off
the medication gradually. Never discontinue
medication without talking to the doctor about
it. For those who have had several bouts of
depression, long-term treatment with medication
is the most effective means of preventing more
episodes.
Dosage of antidepressants
varies, depending on the type of drug and the
person's body chemistry, age, and, sometimes,
body weight. Traditionally, antidepressant
dosages are started low and raised gradually
over time until the desired effect is reached
without the appearance of troublesome side
effects. Newer antidepressants may be started at
or near therapeutic doses.
Early
antidepressants. From the 1960s through
the 1980s, tricyclic antidepressants
(named for their chemical structure) were the
first line of treatment for major depression.
Most of these medications affected two chemical
neurotransmitters, norepinephrine and serotonin.
Though the tricyclics are as effective in
treating depression as the newer
antidepressants, their side effects are usually
more unpleasant; thus, today tricyclics such as
imipramine, amitriptyline, nortriptyline, and
desipramine are used as a second- or third-line
treatment. Other antidepressants introduced
during this period were monoamine oxidase
inhibitors (MAOIs). MAOIs are effective for
some people with major depression who do not
respond to other antidepressants. They are also
effective for the treatment of panic disorder
and bipolar depression. MAOIs approved for the
treatment of depression are phenelzine (Nardil),
tranylcypromine (Parnate), and isocarboxazid
(Marplan). Because substances in certain foods,
beverages, and medications can cause dangerous
interactions when combined with MAOIs, people on
these agents must adhere to dietary
restrictions. This has deterred many clinicians
and patients from using these effective
medications, which are in fact quite safe when
used as directed.
The past decade has seen
the introduction of many new antidepressants
that work as well as the older ones but have
fewer side effects. Some of these medications
primarily affect one neurotransmitter,
serotonin, and are called selective serotonin
reuptake inhibitors (SSRIs). These include
fluoxetine (Prozac), sertraline
(Zoloft), fluvoxamine (Luvox),
paroxetine (Paxil), and citalopram
(Celexa).
The late 1990s ushered in
new medications that, like the tricyclics,
affect both norepinephrine and serotonin but
have fewer side effects. These new medications
include venlafaxine (Effexor) and
nefazadone (Serzone).
Cases of
life-threatening hepatic failure have been
reported in patients treated with nefazodone
(Serzone). Patients should call the doctor if
the following symptoms of liver dysfunction
occur—yellowing of the skin or white of eyes,
unusually dark urine, loss of appetite that
lasts for several days, nausea, or abdominal
pain.
Other newer medications
chemically unrelated to the other
antidepressants are the sedating mirtazepine
(Remeron) and the more activating
bupropion (Wellbutrin). Wellbutrin has
not been associated with weight gain or sexual
dysfunction but is not used for people with, or
at risk for, a seizure disorder.
Each antidepressant
differs in its side effects and in its
effectiveness in treating an individual person,
but the majority of people with depression can
be treated effectively by one of these
antidepressants.
Side
effects of antidepressant medications.
Antidepressants may cause mild, and often
temporary, side effects (sometimes referred to
as adverse effects) in some people. Typically,
these are not serious. However, any reactions or
side effects that are unusual, annoying, or that
interfere with functioning should be reported to
the doctor immediately. The most common side
effects of tricyclic antidepressants, and ways
to deal with them, are as follows:
- Dry mouth—it is
helpful to drink sips of water; chew sugarless
gum; brush teeth daily.
- Constipation—bran
cereals, prunes, fruit, and vegetables should be
in the diet.
- Bladder
problems—emptying the bladder completely may
be difficult, and the urine stream may not be as
strong as usual. Older men with enlarged
prostate conditions may be at particular risk
for this problem. The doctor should be notified
if there is any pain.
- Sexual
problems—sexual functioning may be impaired;
if this is worrisome, it should be discussed
with the doctor.
- Blurred
vision—this is usually temporary and will
not necessitate new glasses. Glaucoma patients
should report any change in vision to the
doctor.
- Dizziness—rising
from the bed or chair slowly is helpful.
- Drowsiness as a
daytime problem—this usually passes soon. A
person who feels drowsy or sedated should not
drive or operate heavy equipment. The more
sedating antidepressants are generally taken at
bedtime to help sleep and to minimize daytime
drowsiness.
- Increased heart
rate—pulse rate is often elevated. Older
patients should have an electrocardiogram (EKG)
before beginning tricyclic treatment.
The newer antidepressants,
including SSRIs, have different types of side
effects, as follows:
- Sexual
problems—fairly common, but reversible, in
both men and women. The doctor should be
consulted if the problem is persistent or
worrisome.
- Headache—this will
usually go away after a short time.
- Nausea—may occur
after a dose, but it will disappear quickly.
- Nervousness and
insomnia (trouble falling asleep or waking often
during the night)—these may occur during the
first few weeks; dosage reductions or time will
usually resolve them.
- Agitation (feeling
jittery)—if this happens for the first time
after the drug is taken and is more than
temporary, the doctor should be notified.
- Any of these side effects
may be amplified when an SSRI is combined with
other medications that affect serotonin. In the
most extreme cases, such a combination of
medications (e.g., an SSRI and an MAOI) may
result in a potentially serious or even fatal
"serotonin syndrome," characterized by fever,
confusion, muscle rigidity, and cardiac, liver,
or kidney problems.
The small number of people
for whom MAOIs are the best treatment
need to avoid taking decongestants and consuming
certain foods that contain high levels of
tyramine, such as many cheeses, wines, and
pickles. The interaction of tyramine with MAOIs
can bring on a sharp increase in blood pressure
that can lead to a stroke. The doctor should
furnish a complete list of prohibited foods that
the individual should carry at all times. Other
forms of antidepressants require no food
restrictions. MAOIs also should not be combined
with other antidepressants, especially SSRIs,
due to the risk of serotonin
syndrome.
Medications of any
kind—prescribed, over-the-counter, or
herbal supplements—should never be mixed
without consulting the doctor; nor should
medications ever be borrowed from another
person. Other health professionals who may
prescribe a drug—such as a dentist or other
medical specialist—should be told that the
person is taking a specific antidepressant and
the dosage. Some drugs, although safe when taken
alone, can cause severe and dangerous side
effects if taken with other drugs. Alcohol
(wine, beer, and hard liquor) or street drugs,
may reduce the effectiveness of antidepressants
and their use should be minimized or,
preferably, avoided by anyone taking
antidepressants. Some people who have not had a
problem with alcohol use may be permitted by
their doctor to use a modest amount of alcohol
while taking one of the newer antidepressants.
The potency of alcohol may be increased by
medications since both are metabolized by the
liver; one drink may feel like two.
Although not common,
some people have experienced withdrawal symptoms
when stopping an antidepressant too abruptly.
Therefore, when discontinuing an antidepressant,
gradual withdrawal is generally
advisable.
Questions about any
antidepressant prescribed, or problems that may
be related to the medication, should be
discussed with the doctor and/or the
pharmacist.
ANTIANXIETY MEDICATIONS
Everyone experiences
anxiety at one time or another—"butterflies in
the stomach" before giving a speech or sweaty
palms during a job interview are common
symptoms. Other symptoms include irritability,
uneasiness, jumpiness, feelings of apprehension,
rapid or irregular heartbeat, stomachache,
nausea, faintness, and breathing
problems.
Anxiety is often
manageable and mild, but sometimes it can
present serious problems. A high level or
prolonged state of anxiety can make the
activities of daily life difficult or
impossible. People may have generalized anxiety
disorder (GAD) or more specific anxiety
disorders such as panic, phobias,
obsessive-compulsive disorder (OCD), or
post-traumatic stress disorder
(PTSD).
Both antidepressants and
antianxiety medications are used to treat
anxiety disorders. The broad-spectrum activity
of most antidepressants provides effectiveness
in anxiety disorders as well as depression. The
first medication specifically approved for use
in the treatment of OCD was the tricyclic
antidepressant clomipramine (Anafranil).
The SSRIs, fluoxetine (Prozac),
fluvoxamine (Luvox), paroxetine
(Paxil), and sertraline (Zoloft)
have now been approved for use with OCD.
Paroxetine has also been approved for social
anxiety disorder (social phobia), GAD, and panic
disorder; and sertraline is approved for panic
disorder and PTSD. Venlafaxine (Effexor)
has been approved for GAD.
Antianxiety medications
include the benzodiazepines, which can relieve
symptoms within a short time. They have
relatively few side effects: drowsiness and loss
of coordination are most common; fatigue and
mental slowing or confusion can also occur.
These effects make it dangerous for people
taking benzodiazepines to drive or operate some
machinery. Other side effects are
rare.
Benzodiazepines vary in
duration of action in different people; they may
be taken two or three times a day, sometimes
only once a day, or just on an "as-needed"
basis. Dosage is generally started at a low
level and gradually raised until symptoms are
diminished or removed. The dosage will vary a
great deal depending on the symptoms and the
individual's body chemistry.
It is wise to abstain from
alcohol when taking benzodiazepines, because the
interaction between benzodiazepines and alcohol
can lead to serious and possibly
life-threatening complications. It is also
important to tell the doctor about other
medications being taken.
People taking
benzodiazepines for weeks or months may develop
tolerance for and dependence on these drugs.
Abuse and withdrawal reactions are also
possible. For these reasons, the medications are
generally prescribed for brief periods of
time—days or weeks—and sometimes just for
stressful situations or anxiety attacks.
However, some patients may need long-term
treatment.
It is essential to talk
with the doctor before discontinuing a
benzodiazepine. A withdrawal reaction may occur
if the treatment is stopped abruptly. Symptoms
may include anxiety, shakiness, headache,
dizziness, sleeplessness, loss of appetite, or
in extreme cases, seizures. A withdrawal
reaction may be mistaken for a return of the
anxiety because many of the symptoms are
similar. After a person has taken
benzodiazepines for an extended period, the
dosage is gradually reduced before it is stopped
completely. Commonly used benzodiazepines
include clonazepam (Klonopin), alprazolam
(Xanax), diazepam (Valium), and
lorazepam (Ativan).
The only medication
specifically for anxiety disorders other than
the benzodiazepines is buspirone
(BuSpar). Unlike the benzodiazepines,
buspirone must be taken consistently for at
least 2 weeks to achieve an antianxiety effect
and therefore cannot be used on an "as-needed"
basis.
Beta blockers, medications
often used to treat heart conditions and high
blood pressure, are sometimes used to control
"performance anxiety" when the individual must
face a specific stressful situation—a speech, a
presentation in class, or an important meeting.
Propranolol (Inderal, Inderide) is a
commonly used beta blocker.
MEDICATIONS FOR SPECIAL
GROUPS
Children, the elderly, and
pregnant and nursing women have special concerns
and needs when taking psychotherapeutic
medications. Some effects of medications on the
growing body, the aging body, and the
childbearing body are known, but much remains to
be learned. Research in these areas is
ongoing.
In general, the
information throughout this page applies to
these groups, but the following are a few
special points to keep in mind.
CHILDREN
The 1999 MECA Study
(Methodology for Epidemiology of Mental
Disorders in Children and Adolescents) estimated
that almost 21 percent of U.S. children ages 9
to 17 had a diagnosable mental or addictive
disorder that caused at least some impairment.
When diagnostic criteria were limited to
significant functional impairment, the
estimate dropped to 11 percent, for a total of 4
million children who suffer from a psychiatric
disorder that limits their ability to
function.
It is easy to overlook the
seriousness of childhood mental disorders. In
children, these disorders may present symptoms
that are different from or less clear-cut than
the same disorders in adults. Younger children,
especially, and sometimes older children as
well, may not talk about what is bothering them.
For this reason, it is important to have a
doctor, another mental health professional, or a
psychiatric team examine the child.
Many treatments are
available to help these children. The treatments
include both medications and
psychotherapy—behavioral therapy, treatment of
impaired social skills, parental and family
therapy, and group therapy. The therapy used is
based on the child's diagnosis and individual
needs.
When the decision is
reached that a child should take medication,
active monitoring by all caretakers (parents,
teachers, and others who have charge of the
child) is essential. Children should be watched
and questioned for side effects because many
children, especially younger ones, do not
volunteer information. They should also be
monitored to see that they are actually taking
the medication and taking the proper dosage on
the correct schedule.
Childhood-onset depression
and anxiety are increasingly recognized and
treated. However, the best-known and
most-treated childhood-onset mental disorder is
attention deficit hyperactivity disorder (ADHD).
Children with ADHD exhibit symptoms such as
short attention span, excessive motor activity,
and impulsivity which interfere with their
ability to function especially at school. The
medications most commonly prescribed for ADHD
are called stimulants. These include
methylphenidate (Ritalin, Metadate,
Concerta), amphetamine (Adderall),
dextroamphetamine (Dexedrine,
Dextrostat), and pemoline (Cylert).
Because of its potential for serious side
effects on the liver, pemoline is not ordinarily
used as a first-line therapy for ADHD. Some
antidepressants such as bupropion
(Wellbutrin) are often used as
alternative medications for ADHD for children
who do not respond to or tolerate
stimulants.
Based on clinical
experience and medication knowledge, a physician
may prescribe to young children a medication
that has been approved by the FDA for use in
adults or older children. This use of the
medication is called "off-label." Most
medications prescribed for childhood mental
disorders, including many of the newer
medications that are proving helpful, are
prescribed off-label because only a few of them
have been systematically studied for safety and
efficacy in children. Medications that have not
undergone such testing are dispensed with the
statement that "safety and efficacy have not
been established in pediatric patients." The FDA
has been urging that products be appropriately
studied in children and has offered incentives
to drug manufacturers to carry out such testing.
The National Institutes of Health and the FDA
are examining the issue of medication research
in children and are developing new research
approaches.
The use of the other
medications described in this booklet is more
limited with children than with adults.
Therefore, a special list of medications for
children, with the ages approved for their use,
appears immediately after the general list of
medications. Also listed are NIMH publications
with more information on the treatment of both
children and adults with mental
disorders.
THE ELDERLY
Persons over the age of 65
make up almost 13 percent of the population of
the United States, but they receive 30 percent
of prescriptions filled. The elderly generally
have more medical problems, and many of them are
taking medications for more than one of these
conditions. In addition, they tend to be more
sensitive to medications. Even healthy older
people eliminate some medications from the body
more slowly than younger persons and therefore
require a lower or less frequent dosage to
maintain an effective level of
medication.
The elderly are also more
likely to take too much of a medication
accidentally because they forget that they have
taken a dose and take another one. The use of a
7-day pill-box, as described earlier in this
brochure, can be especially helpful for an
elderly person.
The elderly and those
close to them—friends, relatives,
caretakers—need to pay special attention and
watch for adverse (negative) physical and
psychological responses to medication. Because
they often take more medications—not only those
prescribed but also over-the-counter
preparations and home, folk, or herbal
remedies—the possibility of adverse drug
interactions is high.
WOMEN DURING THE CHILDBEARING
YEARS
Because there is a risk of
birth defects with some psychotropic medications
during early pregnancy, a woman who is taking
such medication and wishes to become pregnant
should discuss her plans with her doctor. In
general, it is desirable to minimize or avoid
the use of medication during early pregnancy. If
a woman on medication discovers that she is
pregnant, she should contact her doctor
immediately. She and the doctor can decide how
best to handle her therapy during and following
the pregnancy. Some precautions that should be
taken are:
- If possible, lithium
should be discontinued during the first
trimester (first 3 months of pregnancy) because
of an increased risk of birth defects.
- If the patient has been
taking an anticonvulsant such as carbamazepine
(Tegretol) or valproic acid
(Depakote)—both of which have a somewhat
higher risk than lithium—an alternate treatment
should be used if at all possible. The risks of
two other anticonvulsants, lamotrigine
(Lamictal) and gabapentin
(Neurontin) are unknown. An alternative
medication for any of the anticonvulsants might
be a conventional antipsychotic or an
antidepressant, usually an SSRI. If essential to
the patient's health, an anticonvulsant should
be given at the lowest dose possible. It is
especially important when taking an
anticonvulsant to take a recommended dosage of
folic acid during the first trimester.
- Benzodiazepines are not
recommended during the first trimester.
The decision to use a
psychotropic medication should be made only
after a careful discussion between the woman,
her partner, and her doctor about the risks and
benefits to her and the baby. If, after
discussion, they agree it best to continue
medication, the lowest effective dosage should
be used, or the medication can be changed. For a
woman with an anxiety disorder, a change from a
benzodiazepine to an antidepressant might be
considered. Cognitive-behavioral therapy may be
beneficial in helping an anxious or depressed
person to lower medication requirements. For
women with severe mood disorders, a course of
electroconvulsive therapy (ECT) is sometimes
recommended during pregnancy as a means of
minimizing exposure to riskier
treatments.
After the baby is born,
there are other considerations. Women with
bipolar disorder are at particularly high risk
for a postpartum episode. If they have stopped
medication during pregnancy, they may want to
resume their medication just prior to delivery
or shortly thereafter. They will also need to be
especially careful to maintain their normal
sleep-wake cycle. Women who have histories of
depression should be checked for recurrent
depression or postpartum depression during the
months after the birth of a child.
Women who are planning to
breastfeed should be aware that small amounts of
medication pass into the breast milk. In some
cases, steps can be taken to reduce the exposure
of the nursing infant to the mother's
medication, for instance, by timing doses to
post-feeding sleep periods. The potential
benefits and risks of breastfeeding by a woman
taking psychotropic medication should be
discussed and carefully weighed by the patient
and her physician.
A woman who is taking
birth control pills should be sure that her
doctor knows this. The estrogen in these pills
may affect the breakdown of medications by the
body—for example, increasing side effects of
some antianxiety medications or reducing their
ability to relieve symptoms of anxiety. Also,
some medications, including carbamazepine and
some antibiotics, and an herbal supplement, St.
John's wort, can cause an oral contraceptive to
be ineffective.
